This paper proposes a new combined multi-cooling and power generation system (CMCP) driven by solar energy. Carbon dioxide is used as refrigerant. A parabolic trough collector (PTC) employed to collect radiation convert it into thermal The includes supercritical CO2 for production an ejector refrigeration with two ejectors provide cooling at different evaporating temperatures. CMCP simulated ho...
Increasingly, military and civilian applications of electronics require extremely high-heat fluxes on the order of 1000 W /cm2. Thermal management solutions for these severe operating conditions are subject to a number of constraints, including energy consumption, controllability, and the volume or size of the package. Calculations indicate that the only possible approach to meeting this heat f...

A Brayton cycle with, external and internal irreversibilities, is analyzed. Optimization of the dimensionless work with respect to two parameters: the isentropic temperatures ratio and the allocation ratio of the heat exchangers, is performed. The qualitative and asymptotic behaviour of the coupled optimal analytic expressions obtained are presented. Using realistic numerical values of the isen...
